Application filed March 2, 1927. Serial No. 172,067.

.2 form of body bolsterbearing substantially in the shape of a wedge intransverse section and wherein means. are provided at its ends for adusting it up and down thejnatural.

. draw ngs there is shown in F 1g. 11], fragslope ofthe inclined ends ofthe bolster.

One of the objects of the present'invention is to provide the bodybolster bearing with two wings or projections at its opposite ends, andto provide two small plates that cooperate with locking surfaces on theprojections wherebythe body bolster bearing may be adjusted to providethe proper clearance with the rollers of the truck bearing and therelocked in position. I

As is well known to thoseskilled in the 30 art, certain tolerances areallowed in the center plates of. the truck bolsters, and furthermore,certain irregularities may be present in the center plates,.whereby itis necessary to provide means for slightly regulating the body bolsterbearing with regard to the truck bearing- Furthermore, as the .centerplates wear or the body bolster. settles, it isoften found desirable tochange the body bolster bearing in relation to the truck bearing.

With the above objectsin viewand other objects which will. be more fullydescribed, as the specification proceeds, the invention consistsincertain new and novelarrangew. n'ientsand combination of parts, as willbe hereinafter more fully described and pointed'out in the claims:

It might be mentioned at this point that other forms of truck bearingsmight be used with thisbolster =bearing, fithe gist of the 1 inventionbeing that portion oft-he side bearing which, is known as the fbodyibolster Referring now lmore particularly; to the' gist of theinvention, thereis asol'idfcasting; which provided with a fiat base andannp-= iier inclinedsurface, clearly shown in cross. section in Fig. 7.l

, Extending beyond the walls seenthet-wo.wingslor projectionsjlO, thesehaving'the saine inclined plane as the upper surface of the casting. I lw w v I This :casting,iwhioh is bodybearing, is I designed to besecuredto the sloping under j surface, ofthe bqdybolstenll, the upper in-:clined surface being such that. the wear plate 1- 7 onthe baseof thecastingwill be parallel;

with;theupper'surfaces of the rollers .3.

It Will also be noticed, as in 3, that regardless of the set positionof'the casting,

surface of the rollers.

So far the casting, or body bolster bearing just described, is similarto the body bearing as set forthin the two previously referred tocompanion cases, but from this pointit differs from those mentioned.

It might be well torefer to Figs. 4: and 5 for the moment, from which itwill beseen that the wings 10 of the casting are somewhat extended androunded as at 12 on their ends while in each of these wings 10, arefor-med the two slots 13 and 1 1. Also, as ma'y beseen distinctly inFig. 4, the upper surfaces of these ends 10 are provided at theirextremeouter edge with the flange .15.

Still referring to Figs. at and 5, it will also benoticedthat wherethevertical walls of the casting merge with the outstanding wings orprojections 10, there are a plurality of small notches or teeth 16.These teeth of course beingjpresent on both the extensions where theymerge with the walls of the casting 1 Referring now for the moment toFig. 8, there is shown one of the'small cooperative locking plates 17its one edge-18 being slightly'beveled and provided with the teeth 19alongthe'bevel to cooperate with the teeth 16. Itwill be seen that thereare two of these plates, one for each end of'the bearing, but adescription of the one is a description of both.

The opposite edge 20 of the plate 17 is under-cut as-at 21, so" that theedge 20 will ride along the bottom surface of the flange .15 of the wing10 heretofore mentioned.

This little'plate 17 has the two circular openings 22 therein, so thattwo bolts 23 may pass respectively through these openings 22 and fitwithin the heretofore mentioned slots 18 and 14, and then pass upwardlythrough the body bolster 11 and have threaded thereon the lock nuts 2a.

IiiFig. 4 the construction and arrangement is shown partly in sectionand partly in elevation'and reinforcing brackets 25 of the body bolsterare shown directly over the body bearingto take up the stresses at thispoint.

Su pposingnow it is desired to slightly adjust the body bearing withregard to the truck bolster bearing, say from the position showninFig. 1. It will first benecessa-ry to loosen the lock nuts on theseveral bolts and slide the body bearing upwardly or downwardly of theincline ofthe-bolster 11, this being possible as the plates 17 may beslight- 1y pulled away from the wings 10 so that the teeth16 and 19 willnot mesh while the; aforementioned slo'tsi'n the wings 1O permit 1 thebearing-to be moved within the limits (the length of the slots), afterwhich the little plates with their teeth will engage with the teeth 16and the nuts 2 1 pulled up tightly on thebolts to thereby clamp the bodybean ing in place. ()fcourse these little plates with the teeth willprovide against any sl1pping or, sliding movement of the bearing afterthe bearing is once locked in position.

Fromthe foregoing, it will be seen that I have provided a side bearingwherein the body bearing is inclined to correspond with the naturalinclination of the body bolster and whereby it may be adjusted withincertain limits along this inclination, the base or wear plate ofthebearing, however, at all times remaining parallel with the surface ofthe rollers.

Furthermore, it willbe seen that the bearing may-be adjusted fromtime totime to allow for the wear or to-allow forthe settling of the bolster orfor any other reason, so that the proper clearances may be maintainedthroughout the life of the hearing.

it will also be seen that the manner of ad justing the bearings is excedingly simple d there are but few parts to be manipulated during theadjustment.

Many slight changes might be made, without in any way departing from thespirit and scope of the invention.

Having thus described the same what I claim as new and desire ,to secureby Letters Patent is: 1. A side bearing comprising a truck bearing and abolster bearing, the bplster hearing being wedge shape in crosssectiouand provided with wings at its end, said wings provided withslots therein and said wings also provided with a row of teeth, a smallplate underlying and cooperating with each wing, teeth on said platesand each plate provided with an opening, means adapted to )ass throu hthe resoective ilates and slots a: l l

said wings lying in an inclined plane, the wings provided with a flangeat one edgeand teeth at the opposite edge, each of said wings providedwith transverse slots, small clamping plates provided with teeth-andundercut the casting may be moved up and down the said body tion.

A side bearing comprising in part a body bearing, the said body bearinghaving bolster and looked in a set posia base and an inclined uppersurface, Wings on said body bearing and located at the opposite endsthereof and lying in an, inclined plane, each of said wings providedwith two transverse slots, said Wings provided with a plurality of small'teethon their under surface, and underlying clamping plate for eachWing also provided with cooperating teeth, bolts passing through saidplates and through said slots, whereby the said body bearing isadjustable with relation to said plates and means for clamping theplates and the body bearing to a bolster.
